Neosho River Tree Ring Chronology from Oklahoma

Tree ring width measurements from the Neosho River region in Oklahoma, United States, used for paleoclimate reconstruction. The chronology covers a 307-year period from 275 to -32 calendar years before present. Data is archived by the NOAA National Centers for Environmental Information's World Data Service for Paleoclimatology.

Use Cases

• Reconstruct past precipitation or drought indices for Oklahoma using the tree ring width time-series.
• Calibrate regional climate models by comparing the chronology's growth patterns with known historical climate events.
• Analyze the frequency of extreme growth years (narrow or wide rings) as proxies for climatic stress or favorable conditions.
• Cross-date and validate other tree ring chronologies from the central US using the established ITRDB OK001 series.

Strengths

• Covers a continuous 307-year period (275 to -32 BP).
• Part of the authoritative International Tree-Ring Data Bank (ITRDB) collection.
• Managed and archived by NOAA NCEI's World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends 32 years before present (1950 CE), lacking recent decades.
• Geographic scope is limited to a single site (Neosho River, Oklahoma).
• Raw sample size, replication statistics, and measurement precision are not detailed in the provided metadata.
